An Eidos is a bonded character unit. In the Final Closed Beta, your first 5-star Eidos or Anima is guaranteed to be the current limited one, and pulling the limited Eidos lets you claim the matching Anima Companion free.
What is an Eidos?
An Eidos is a bonded character unit you add to your lineup. The official site uses the term next to Anima, and the beta guarantee covers both, which tells you they are separate unit types in the same team system.
Up to three Eidos deploy alongside your Anima in battle and cast timed skills, per press hands-on coverage [verify].
What does the 5-star guarantee mean?
The official wording: the first 5-star Eidos or Anima a player obtains is guaranteed to be the current limited one. It is a one-time rule inside the Final Closed Beta, not a permanent pity system.
Read it literally. It guarantees the identity of your first 5-star, not a rate, not a soft pity, and not a launch policy.
How do the two banner families work?
HoYoverse runs two limited banner families, the Eidos Event Bond and the Anima Event Bond, and both were adjusted for the Final Closed Beta. That is official.
Press coverage says the families use separate tickets and separate pity, with a ticket currency called Nexus Trace. Treat those details as reported, not confirmed, because HoYoverse has not published the shop rules [verify].
How does the free Anima Companion work?
Obtain the current limited Eidos and you can claim the matching Anima Companion for free. The companion is tied to that Eidos, so it is not a generic selector.
The official text does not say whether the companion is a separate unit slot, a skin, or a battle partner. Fielding an Eidos with its Companion Anima is reported to grant extra effects, which suggests a battle pairing [verify].
What are the rates and pity numbers?
Not published. There is no official base rate, hard pity, soft pity, or 50/50 wording for this game yet.
This site will publish a table when HoYoverse does. Until then, a number you see elsewhere is either borrowed from another game or invented.
Is this a spending guide?
No. This page explains how the bond and guarantee mechanics work. It does not rank value, recommend a purchase, or tell you how to spend.
